When a client arrives for their appointment, you should update their appointment record so you can track how long the client waits.

The Appointment Monitoring Station displays.
The status of the appointment changes to ARRIVED.
Notes:
If you use the Auto-Page System and the employee has a pager, the employee receives a message to inform them that the client has arrived.
If you marked the client as arrived by mistake, open the Appointment Book, right-click on the client's appointment and select Arrived > Undo Arrived to cancel the status change.
To track the time that has elapsed since the client was marked as arrived, check the Timer field next to the appointment.
